Not 100% correct.

You can get a fixed IP on a business service, but expect to pay muuuuuucccchhhh more per month for the luxury.

It also also been known for them to require it be changed when they change network address assignments.

Not 100% correct!
it's an extra £10 a month for the so-called "fixed" IP address on Business Broadband. "Fixed" means "will stay the same until we move your connections to a different UBR, or do another network reorganisation, or some other reason". They now commit to telling you in advance about this change of IP address, whereas previously you found that your Exchange Server didn't work any more on a Monday morning. We've 'only' had it happen a total of three times on three separate cable lines in five years...

In practice thats no different to what a residental customer gets.

Typically any VM ip will stay the same unless a reseg, move between overlay and legacy or the modem is off for a 'long' time. It will also change if the connecting MAC changes eg. change cable modem but that is also something that should be rare.

With the recent upgrade to 30MB (and thus a new modem / move to DOCSIS 3) my IP has changed. Prior to the upgrade, I had the same IP address for just shy of 2 years.

and would have been the same for a business user. Your ip will very likely stay the same now unless you downgrade again or change modem.

Sadly I think it's just one of those things.

Sure it can be annoying but many other residential ISPs don't offer static IP's either.

Just a thought, rather than providing an IP address to the admins where you work, are you able to maybe give them a domain name instead and use something like DynDNS?

I guess the rationale behind all this is that an IP address is a valuable resource not to be wasted but with "always on" connections surely a dynamically assigned IP address is going to be captured and retained for quite some time so why don't we all have a fixed IP address and be done with it?

Could you please explain in detail your observation about DynDNS or refer me to other URLs where I could learn more about this? It might be a solution.

Sure, basically DynDNS (and other such services such as NoIP and a whole load of other providers) basically offer a DNS hostname which resolves to your IP address. I've been using DynDNS now for around 6 or 7 years.

How it works is there is either a small client app which runs on your PC (or server) which detects your IP address on the internet, it then sends this IP address to the DynDNS server which registers it against a host name. You can then look up the hostname and it resolves to your IP address. It checks every couple of hours I believe and if the IP address changes it updates the entry. Usually most routers have a client built in too which do the same thing (this is how I do it with my Virgin provided Netgear router) so when my IP changes it notifies the DynDNS server.

Generally you can get a basic Dynamic DNS service for free (DynDNS offer a basic free service) but if you want something a bit more fancy (such as a your own domain name pointing to an IP) then it costs something like $12 a year.

Thinking about it though, your work system may do a reverse DNS query in which case it would get a Virgin Media host name rather than a DynDNS address. But on the other hand it could be worth trying since it's free and only takes a couple of minutes to setup.
